BELT-FASTENER.

SPECIFICATION forming part of Letters Patent No. 316,668, dated April 28, 1885.

Application filed May 7, 1883. (No model.) Patented in England December 9, 1882, No. 5,901 in France April 18, 1883, No. 154,936,

To all whom, it may concern.-

Be it known that I, WILLIAM HENRY SLEEP,

a subject of the Queen of Great Britain, re-' siding at St. Germans, in the county of Cornwall, England, have invented new and useful Improvements in Belt-Fasteners, of which the following is a specification.

My said invention has reference to improvements in the construction of connectors or fasteners for uniting the ends or intermediate lengths or sections of driving and other straps, bands, belts, or cords of any section, and whether composed of one or more pieces or lengths, whereby sewing, lacing, riveting, or other such like methods of connecting are dispensed with, and which methods, besides occupying considerable time, also diminish the strength and durability of the belting material of whatever kind, owing to the necessity for piercing the same to retain the fastener.

By my invention, piercing being entirely dispensed with, the strength of the material is fully maintained, while provision is also made for quickly,economically, and effectively securing the ends of the bands or belts by an arrangement which when applied is both selfacting and self-holding, or which may be tightened or held in position by means of screws, bolts, or rivets."

In carrying out my invention I employ one or more eccentric rollers, tongues, or holders of suitable shape, and suitably held together at the ends by means of straight-edged or concavo-convex plates, which may be made with or without bosses, and in either case may be grooved or channeled for the reception of the ends of the bands or belts and placed on their edge, rivets or screws passing through the plates and bosses and longitudinally through the rollers, tongues, or holders, or may terminate a suitable distance from the ends of the rollers, tongues, or holders, such means being adopted for expanding or contracting the connector or fastener longitudinally; or suchlrollers, tongues, or holders may be made with studs or rivets in the same at each end to connect the plates; or the plates may be made with studs or rivets in the same for connecting the rollers, tongues, or holders In order to enable my invention to be fully understood and carried into practice, I will proceed to describe the same by reference to the accompanying drawings, which represent views of belt-fasteners constructed according to my improvements.

Similar letters in all the figures represent similar parts.

Figure 1 is a plan of a belt-fastener applied to a belt and showing the arrangement when: two eccentric plates, tongues, or holders are employed. Fig. 2 is a transverse section of same on line a: m, Fig. 1. Fig. 3 is a section on line A B of Fig. 1, and Fig. 4 is a crosssection showing the tongues opened, the belt not being shown in Figs. 3 and 4:. Figs. 5 to 20, inclusive, are modifications.

In these figures a a are two eccentric plates, tongues, or holders formed or provided with projections or teeth b b, as shown, and moving or rotating on the rods or bolts 0 a, connected together by the end plates or pieces, d d. The inner lower edge of each end piece is beveled or cut away at e e, for the purpose hereinafter described.

To make use of a belt-fastener of this construction, the tongues a a are turned on their rods or bolts 0 c in the direction of the arrows, as shown at Fig. 4, and the ends of the belt or strap or section of belt or strap f to be connected or fastened together are placed together fiatwise, and are passed up between the two eccentric tongues or holders a a, the belt oifstrap f being then pulled downward,and the drivingstrain being brought upon the belt, thettongues or holders a a being eccentric to the rods or bolts 0 c on which they turn will be brought fast to the loose pulley, or vice versa.

The fastener shown in plan and end views in Figs. 5 and 6 is substantially the same as that shown in Figs. 1, 2, 3, and 4, except that one end of the rods or bolts 0 c are screwthreaded, and screw into the bosses g g of one of the end plates dd. This arrangement allows of the fastener being contracted longitudinally by screwing up the bolts 0 a so as to bring the ends of the fastener within the sides of The action is otherwise of belt-fastener, showing thetwoends-offa belt; Fig. 18, a plan of the under side ofithe the belt f, as shown.

the same as that hereinbefore .described, and

therefore needs no further description.

Instead of the rods or bolts passing from end 7 to end, as hereinbefore described, each tongue scribed when referring to Figs. 5 and 6.

or holder may be connected to the end plates, at d, by two screw-bolts, c c c o, as shown in plan and end at Figs. 7 and 8, the arrangement being for the same purpose as above de- In these figures the edges of the tongues are ser rated to grip the belt. e

For wide belts, where it is advisable toemploy a number of fasteners, I form the end plates, (1 d, of a saddle or half-moon shape, as shown in Figs. 11 and 12, the hollow part h passing over the turned-up ends of the belts, as shown. V

Figs- 13 and 14 show a plan and cross-section 'of a fastener in which only one movable tongue or holder (1 and one rod or bolt 0 are employed,.the end plates, d (1, being conso as to grip the ends of the beltf the holder and the fixed plate 2.

nected together or formed; in one- -piece by or with the cross-piece or fixed plate 12, formed with serrations or teeth, as shown, the strain on the belt causing the ends to be gripped between the tongue a and the fixed plate 41. When only one tongue is employed, I sometimes employ the arrangement shown in plan and crosssection at Figs. 15 and 16, which is substantially the same as that shown in Figs. 13 and 14:, except that screws j j are employed to move the tongue a so as to grip the belt between the tongue at and the fixed plate i, and when once gripped is self-holding; or,where a fixed plate is employed, instead of employing 'a' tongue orholder a turning on a rod or bolt 0, as shown in Figs. 15 and 16, the holder may consist of a loose plate, 70, (shown in Figs. 17 ,1 18, and 19,) screwsjj'serving to press-the holder or loose plate It, .as in Figs. 15 and 16,

Having thus described my said. invention,

- and the best means-withwhich I amacquainted for carrying the same into effect, Iwould have it understood that what Iclaim is-,-

A belt-fastener havingntwo'end plates, screwthreaded rods passing through said plates for: adjusting the same," and curved swinging. tongues or plates. provi'dediwi-th bitingf-sur-y between faces, and pivoted to said rods, substantially) as described.
